Hmm, this is most strange. I cannot reproduce this behavior on my machine.
 I tried re-cloning the repository and reinstalling to see if I was somehow
using files that had not been published to GitHub.

I would suggest double-checking that you are using the right version of the
code and that nothing else is getting mixed into the package somehow:

   cd path/to/RTikZDevice
   git checkout experimental/metapost     # Checkout the metapost branch

   # Make sure it matches what I posted on GitHub. This *will* destroy
   # any local modifications, so stash them on another branch if you want to
keep them.
   git reset --hard origin/experimental/metapost
   git pull origin   # make sure the branch is up to date

   make install

If you are still getting problems after that, let me know which OS and
version of R you are using and I can try to reproduce the error.
